Description

[Technical field]

[0001] The present invention relates to a skin winding system, and more particularly to a skin winding system for vehicle interior members. [Background technology]

[0002] Conventionally, in vehicle interior components (e.g., console boxes, glove boxes, door trims, etc.) for automobiles and the like, the surface of a base material is covered with a skin made of various materials (e.g., woven fabric, synthetic resin, genuine leather, etc.) to enhance a sense of luxury. When this skin covers the base material, a terminal treatment is performed in which the excess end of the skin, which is formed to be slightly larger than the base material, is folded inside the base material and fastened with a fastening member. This terminal treatment work has been mechanized, for example, as shown in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-68349 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the technology of Patent Document 1 described above, in the straight line portions (straight sections) of the substrate, the holding portion that folds the excess end portion of the skin inwardly of the substrate follows the excess end portion of the skin over substantially the entire area of ​​the straight line portions of the substrate. On the other hand, in the corner portions (curved sections) of the substrate, the holding portion that folds the excess end portion of the skin inwardly of the substrate follows the excess end portion of the skin only in a partial area of ​​the corner portion of the substrate. As a result, wrinkles may occur in the skin in the areas where the holding portion does not follow the excess end portion of the skin (the remaining area excluding a part of the corner portion). This may result in a poor finish of the skin in the corner portions of the substrate.

[0005] The present invention is intended to solve such problems, and has an object to provide a skin winding system that can provide a good finish to the skin at the corners of the substrate. [Means for solving the problem]

[0006] According to one feature of the present disclosure, a skin winding device for vehicle interior members includes a base material setting section capable of setting the base material in a state in which the surface of the base material of the vehicle interior member is covered with the skin, and a base having a peripheral portion having a plurality of guide grooves in a radial direction at the periphery of the base material setting section. The device further includes a group of blocks that slide via sliders arranged in the guide grooves of the base so that the excess end of the skin in a state in which the surface of the base material set in the base material setting section of the base can be folded inward along the edge of the base material. The device further includes a plurality of actuators that individually slide each slider of the group of blocks. The group of blocks includes a straight block corresponding to a straight portion of the edge of the base material, and a plurality of corner block pieces corresponding to a chamfered R-shaped corner portion of the edge of the base material. The corner block pieces are rotatable with respect to the sliders, and are slidably connected to adjacent corner block pieces via a connecting member without any gap. When a plurality of actuators corresponding to a plurality of corner block pieces are driven simultaneously and at the same speed, the plurality of corner block pieces slide and turn by the connecting member so that the edge of the plurality of corner block pieces on the base material side follows the R-shape of the corner portion of the base material.

[0007] Therefore, when the actuators corresponding to the corners of the substrate are driven simultaneously and at the same speed, the multiple corner block pieces follow the excess end of the skin in a continuous state along the edge of the corner of the substrate (over almost the entire area of ​​the edge of the corner). Therefore, the multiple corner block pieces fold the excess end of the skin corresponding to the corner of the substrate in a continuous state along the edge of the corner to the inside of the substrate. As a result, there is no risk of wrinkles occurring in the skin at the corner of the substrate. Therefore, the finish of the skin at the corner of the substrate is good.

[0008] According to another feature of the present disclosure, the connecting members are connected by a spigot structure.

[0009] Therefore, even if adjacent corner block pieces connected by the guide and the guide groove slide, they can be prevented from coming off each other. Therefore, the multiple corner block pieces can be easily made to conform to the excess end of the skin. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to Figs. 1 to 8. In the following description, a console box (not shown) for an automobile or the like will be described as an example of a vehicle interior member. Therefore, in this embodiment, the skin winding equipment 1 will be described as an equipment for winding a skin 15 on the surface of a base material 10 of a lid 5, which is a cover for a box body of a console box. Below, the lid 5 and the skin winding equipment 1 will be described separately.

[0012] First, the lid 5 will be described. As shown in Fig. 1, the base material 10 of the lid 5 is formed in a rectangular shape having straight line portions 11 made up of four sides. The locations where these straight line portions 11 intersect become chamfered R-shaped corner portions 12. In other words, the base material 10 has four straight line portions 11 and four corner portions 12.

[0013] 1 and 4, the skin 15 has an excess end 16 on its periphery, and is formed to be slightly larger than the surface of the substrate 10. This excess end 16, which is a portion formed to be larger, can be folded inside the substrate 10 and attached to the substrate 10. This excess end 16 makes it possible to perform terminal processing of the skin 15 in a state where it covers the surface of the substrate 10. Various materials are considered for the skin 15, such as woven fabric, synthetic resin, genuine leather, etc.

[0014] Next, the skin winding equipment 1 will be described. As shown in Figs. 1 and 4, the skin winding equipment 1 includes a base 2, a block group 3, and a plurality of cylinders 4 that are actuators. The base 2 is a platform-shaped receiving jig that includes a substrate setting section 20 that can set (hold) the substrate 10 with the surface of the substrate 10 of the lid 5 covered with the skin 15, and a peripheral section 25 that has a plurality of guide grooves 26 in the radial direction on the periphery of the substrate setting section 20. The surface of the substrate 10 is the surface of the lid 5 of the console box that is located on the passenger compartment side. Each of the plurality of guide grooves 26 includes (is arranged with) a slider 27 that slides along the longitudinal direction.

[0015] 1, the block group 3 includes a straight block 30 corresponding to (located at) the straight portion 11 of the edge of the base material 10, and a plurality of (four in this example) corner block pieces 35 corresponding to (located at) the chamfered corner portions 12 of the edge of the base material 10. The straight block 30 is formed, for example, in a substantially rectangular shape, and is provided so as to correspond to the four straight portions 11, respectively. That is, the straight block 30 is provided in a total of four places. The lower surface of the straight block 30 is fixed to the upper surface of the slider 27.

[0016] As shown in Fig. 2, the multiple corner block pieces 35 are each formed, for example, in any one of a substantially triangular shape to a substantially pentagonal shape, and are provided so as to correspond to the four corner portions 12, respectively. That is, the multiple corner block pieces 35 are provided in a total of four locations. One side surface 35a of the corner block piece 35 is provided with a guide 36 having a substantially L-shaped cross section. The other side surface 35b of the corner block piece 35 is provided with a guide groove 37 having a substantially L-shaped cross section into which the guide 36 of the adjacent corner block piece 35 can be inserted. The guide 36 and the guide groove 37 have a spigot-joint structure that allows them to slide relative to each other, and correspond to a "connecting member" described in the claims.

[0017] 2 and 6, adjacent corner block pieces 35 can be slid by inserting the guide 36 of one corner block piece 35 in the guide groove 37 of the other corner block piece 35 in the planar direction. This allows the corner block pieces 35 to be connected to the adjacent corner block pieces 35 without any gaps via the connecting members, the guide 36 and the guide groove 37.

[0018] 3 and 4, the bottom surface 35c of the corner block piece 35 is provided with a circular recessed hole 38. The recessed hole 38 is provided with a bearing 39 having an inner ring 39a and an outer ring 39b. The outer ring 39b is fixed to the inner circumferential surface 38a of the recessed hole 38. The inner ring 39a is fitted with a bolt 28. The bolt 28 is fixed to the tip of the slider 27. Therefore, the corner block piece 35 is capable of turning (rotating) with respect to the slider 27 via the bearing 39.

[0019] 1 and 4, the cylinder 4 includes a cylinder body 40 and a rod 41 that can advance and retreat relative to the cylinder body 40. A cylinder 4 is provided for each straight block 30 and corner block piece 35. The tip of the rod 41 is fixed to the slider 27. Therefore, when the cylinder 4 is driven (the rod 41 is advanced or retreated), the straight block 30 and the corner block piece 35 slide individually along the guide groove 26 via the rod 41. The skin winding equipment 1 is made up of the base 2, block group 3, and multiple cylinders 4 described above.

[0020] Next, the operation of the skin winding equipment 1 will be described. As shown in Figs. 1 and 4, first, the substrate 10 is set in the recess 21 of the substrate setting section 20 of the base 2 with the surface of the substrate 10 covered with the skin 15. In this state, as shown in Fig. 4, the excess end 16 of the skin 15 stands up from the periphery of the substrate 10. Next, the cylinder 4 corresponding to the straight portion 11 of the substrate 10 is driven (the rod 41 is advanced) to slide the straight block 30. Then, the straight block 30 folds the excess end 16 of the skin 15 corresponding to the straight portion 11 of the substrate 10 along the edge of the straight portion 11 of the substrate 10 (over almost the entire area of ​​the edge of the straight portion 11) toward the inside of the substrate 10.

[0021] Next, the cylinders 4 corresponding to the corner portions 12 of the substrate 10 are driven simultaneously and at the same speed. Then, the four corner block pieces 35 are slid by the sliders 27, respectively, and rotate relative to the sliders 27 by the bearings 39. That is, from the state shown in Fig. 6 to that shown in Figs. 7 and 8, the four corner block pieces 35 move continuously (without interruption) toward the corner portions 12 so that their edges on the substrate 10 side follow the R-shape of the corner portions 12 of the substrate 10.

[0022] Therefore, as shown in Figs. 5 and 8, the four corner block pieces 35 fold the excess end portions 16 of the skin 15 corresponding to the corner portions 12 of the substrate 10 inwardly of the substrate 10 in a continuous manner along the edge of the corner portion 12 without interruption (over almost the entire area of ​​the edge of the corner portion 12). These foldings apply tension to the skin 15 covering the surface of the substrate 10. Therefore, the appearance of the skin 15 covering the surface of the substrate 10 can be improved. Finally, the excess end portions 16 folded inwardly are fastened to the inside of the substrate 10 by fastening members (not shown). In this manner, the end treatment of the skin 15 covering the surface of the substrate 10 can be performed.

[0023] As described above, according to the skin winding equipment 1, the cylinders 4 corresponding to the corners 12 of the substrate 10 are driven simultaneously and at the same speed. Then, the four corner block pieces 35 follow the excess end 16 of the skin 15 in a continuous state along the edge of the corners 12 of the substrate 10 without interruption (over almost the entire area of ​​the edge of the corners 12). Therefore, the four corner block pieces 35 fold the excess end 16 of the skin 15 corresponding to the corners 12 of the substrate 10 in a continuous state along the edge of the corners 12 without interruption to the inside of the substrate 10. Therefore, there is no risk of wrinkles occurring in the skin 15 at the corners 12 of the substrate 10. Therefore, the finish of the skin 15 at the corners 12 of the substrate 10 is good.

[0024] In addition, the guide 36 and the guide groove 37 have a spigot structure that allows them to slide relative to each other. Therefore, even if the adjacent corner block pieces 35 connected by the guide 36 and the guide groove 37 slide, they can be prevented from coming off each other. Therefore, the four corner block pieces 35 can be easily made to follow the excess end portion 16 of the skin 15.

[0025] Although the embodiment has been described above, the present invention is not limited to this embodiment and can be embodied in various other forms. In the embodiment, a console box of an automobile or the like has been described as an example of a vehicle interior member. Alternatively, a glove box, door trim, or the like of an automobile or the like may be used. Also, in the embodiment, an example has been described in which the straight block 30 is slid, and then the four corner block pieces 35 are slid. Alternatively, the straight block 30 and the four corner block pieces 35 may be slid simultaneously.

[0026] In the embodiment, the cylinder 4 is described as an actuator for sliding the straight block 30 and the corner block piece 35. Alternatively, a ball screw, a ball nut, a motor, or the like may be used for sliding. In the embodiment, four corner block pieces 35 are described as an example. Alternatively, any number of corner block pieces (e.g., two, three, five, etc.) may be used as long as there is a plurality of corner block pieces. [Explanation of symbols]
